Marble and granite are both popular, but which is the best all-around and why? There are two issues here, hardness and durability. Harder than a knife, more powerful than a locomotive, able to…well, harder than a knife and able to resist chipping due to bumps, is one key element. Granite, which is composed of silicate minerals, silica and oxygen, is pretty tough stuff, while marble made of calcium carbonate is much softer than, say, a steel blade. Round one to granite.The second determining factor is chemical resistance. As we said before, marble is made of calcium carbonate, the same stuff that limestone caves are made of, and will dissolve in water after a relatively short span of time. Granite on the other hand, composed of silicate minerals stands up to the test. The winner and champion, rocking the competition by a landslide, is granite! No pun intended of course.
